Filed: 1984-07-31
Abstract: The invention relates to a protective device for the ends of pipes to be joined to one another, in particular earth field pipes, whose end faces are constructed with an annular welding bevel and an annular web. In order to guarantee a reliable protection of the pipe end, in particular of the web in the case of pipes with a welding bevel and web, also during the handling of such pipes with the aid of hooks hooked into the pipe end, the protective device has a cylindrical part with or without a bottom, which part can be inserted inside the pipe and has a first annular flange which covers the end face of the pipe and is adjoined by a second annular flange which grips over the outside of the pipe end. The cylindrical part or the cylindrical part and the first annular flange is or are constructed so as to be reinforced at least in the region of the transition from the cylindrical part to the first annular flange or in the region of the annular web to be protected. To improve the protective effect, an angle profile is provided which is bent to form an open ring, whose one limb rests against the inside of the cylindrical part which can be inserted inside the pipe and whose other leg rests against the outside of the first annular flange. A spreading device presses the limb firmly against the inside of the cylindrical part. <IMAGE>

Title: Output stage for signals symmetrical about the neutral line
Inventor: NEUDERT BEATE DIPL ING
IPC: H03F3/26
Filed: 1984-08-23
Abstract: The invention relates to an amplifier circuit which is specifically suitable for electromedical purposes. The aim is to improve the technical parameters of the transmission behaviour of the entire output stage. There is the object of providing a circuit arrangement by which signals of a generator which are symmetrical about the neutral line can be amplified, it being intended for the output to be of constant current and resistant to short-circuits. The object is achieved by using a rectifier circuit to separate the signals into positive and negative components, which pass to an optocoupler. In a push-pull transistor circuit with respectively separate power sources and a common load resistor, a separate amplification of the components and composition takes place in the load resistor. Resistance to short-circuits is achieved by incorporating series resistors. The field of applications is that of amplifier technology, preferably for use as an output-stage amplifier for devices producing stimulating currents. <IMAGE>

Title: Television picture production by rotation or other suitable movement of one or more LED strips
Inventor: SCHMALENBACH PETER DIPL ING
IPC: H04N3/10
Filed: 1985-08-14
Abstract: Until now, television pictures have been almost exclusively produced by the Braun tube. The few methods in which the picture is not produced directly in the tube nevertheless work at some point by deflecting an electron beam in a tube which is pumped free of air. With this invention, a completely new method of picture production is presented. If two strips of LEDs are moved, one after the other, from top to bottom, before the eyes of the viewer, the first strip displays the first half-picture of the European television standard, and the second strip displays the second half-picture. Even with only 60 LEDs per line (= 60 picture elements), the picture quality is astonishing. This is also because in this method all 625 lines are displayed, irrespective of the number of picture elements per line. In the experimental device, 2 LED strips were used, fixed to a rotating shaft and set at 180 DEG  to each other. All the control electronics are also fixed to the shaft and rotate during picture production. A DC motor drives the construction. Picture steadiness on the virtual picture drum (= vertical hold control) is achieved by controlling the number of rotations of the motor. Pulses output by the machine are compared with the vertical synchronisation pulses of the transmitter. <IMAGE>

Title: Drive and brake device for rail vehicles
Inventor: FREDERICH FRITZ PROF DR ING
IPC: B60L3/10
Filed: 1985-09-05
Abstract: In order to generate the greatest possible drive or braking forces in the wheel/rail contact and in order to minimise the wheel and rail wear caused by longitudinal forces and the unavoidable longitudinal slip, skidding and locking of the wheel, which can be caused by variation of the adhesion conditions at the wheel/rail contact point, must be prevented. For this purpose the drive and braking torque is adjusted to the currrent requirements. The variation of the adhesion longitudinal forces is measured and fed to the closed loop control. The closed loop control can then adjust the torque of the drive or brake before any fluctuation of the adhesion becomes detectable from a change in the speed of rotation. <IMAGE>
